Tf all whom 'maw come/ivf,

l, luiers 'lli il. liess? niteil fv'tfitesa residing; e, the city of Greater lievi York., eoontyof Biella/ione, State ot' New York., have inverited new and useful liiiprovements Film-Guiding eviees, which the foleiw" ing e, speemeetion.

This invention relates to o. film guiding device for motion picture "eeting mw oliiries mid has for its. object' to provide e film` guide'ior the ed'e of the tilm ivliieli Will not ive injured oy tl'ie friction produced by the repidiy moving film and which Twill not adhere to the film or otherwise dead age it.

In moving picture proieeting ii'iiieliinee as et present constructed. the file" are pleeed in the form. of e reel in e fire-pro mager zine forming peri; of the iriecleine', and from:

gtliisfeieigoziiie the end of e. film is fed 'from the, maeliine.

, now corr use,

through Suitable guioirig device, felled in the trade e magazine veli/'ef7 thence through a, film feeding device met the projection aperture and through magazine .valve int-e the receiving erigezcine supported ori the lower `part of the machine, it has ybeen eimd in practice tiret the edge of e lm moving rrapidly ir. Contact with the brass forming the edgeo the valve wears the seme so that in :i little ivliile it presents a v ]:eggecl surface, whicha iiiiiese at' once re paired, or replaced Seriously demagee the edge of" l'f A Valve the manner oi omanimee, is shown 'i Wer 35%?601 valve eiiowie iii i'oiieation ie semeeonfigiiretion but is ezine in the Seme Way granted l tliedrevv what modiiied. mounted with 'its iipjerJ roll/- within the magazine end its levier rollers below'tlie eme.

One of tin rollers is mounted in inclined slots as shown in l, the purpose of which is to cause the roller to press egtinet the film so that in crise the film @etoiles lire during its mevement from ooe reel to the other, the rollers will en; tingiiisli the 'Haine by reason of their eliilAA ing effect, thereby preventing the fiame reaching the reel of the film iii the inegi Zine and causing e serious cenfiefretioii.

The iaody il oi the valve is provided 'with integral flanges beyond the roller support-- ing brackets providing e. suitable supporting Surface when. the valve is attached to 'fixe rhagaziiie in tile manner indicated l 't The. betf-Jveeri oase and enel; oi

The -rollers 3 ore slightly enlarged et eaeii In ordinary operation the edge of the film e is guided by the inner face of the web Q to maintain the film in proper alinement with the feed rollers. It has been found by long experience that the edge of the film outs into of the piece 5 which are lient over the enc..

to 'form :i groove therein, in a eonipzirziti\'ely short time. This groove7 while not dauw aging: the valve to an extent to seriously wenken the Seme, necessitates the immediate replacement oi' a valve for-the reason that. the roughened surface of the hrsiss muses thekfilni to weer on 4the edge und :xls-5o not infrequently splinters in the surface catch the film and so hinder its feeding!r that the feed sprockets teer out the margin ofthe film beyond the holes in which they engage, sometimes entirely ruining! :i lan-Ie portion of the film. To obvinte this dili'eulty i provide a supplemental guiding' attachment 'for the magazine valve which keeps the edge of 'the lni out of Contact with the hiess. This guiding' attachment. is shown detached in Fig. 3 and comprises a freine piece in which is supported e vsinzill piece of glass il. being held in place hy theends, 5 i.

of the glass to 'form suitable ways therefor. The edges o1 the piece 5 helen' `the glass f3 are bent over in e similar manner at 3 te tit the edges ef the wel) 2 as shown in Fig'. l. The glass 6 is thicker than the metal or' the web 2 and consequently its fece projects heyond the face ot' the wel) so that the edge of the film is guided by theglzxss and held out of Contact with the web. here found by experiment; that the smooth surface nf the glass affords much less frietional resistance to the passage of the film than the brass surface se that there is much less weer on the edge of the Hlm, and' furthermore, 'the glass heine` e( great deel harder is nel; cut or .roughened by the film and preserves its smooth glazed surface throughout the ereli nary life of e. projecting' machines have shown my improved. attaelnnent as applied to only one edge of e magazine valve, lint it will bennderstood that it may he applied at both edges if desired, pai-tienn larly it' the valve is closed et both edgesas is sometimes the l have designed my improved guide piece as e seperate piece freni the magazine valve ,ein
